SPRNG TIRE.

Application* led September 24, 1920. Serial No. 412,424.

To all whom t may concern.'

`Be it known that I, JACOB A. BRADLEY, a citizen of the United States, and resident oi? Milwaukee, in the county ot Milwaukee and State of l/Visconsin, have invented certain new and useful improvements in Spring Tires; and l do hereby declare that the following is a i'ull, clear, and exact description thereof.

My invention relates to improvements in automobile tires, and has ttor an object to provide a tire which will be simple in construction, and which will embody a plurality of springs carried by the rim of a wheel and which are protected by a casing, thus providing a puncture proof tire.

The object of my invention, stated spe cically, is to arrange the parts in such a manner that the springs may be easily de' tachable for replacement.

Other objects and advantages will be apparent as the nature of the invention is more fully disclosed, and it will ot course be understood that certain changes in the structure of the invention may be resorted to within the scope of the appended claim.

ln the drawings forming a portion O' this speeiiication, and in which like numerals of reference indicate similar parts in the several views,

Figure l is a partial view of a wheel showing in section one embodiment of my invention, and

Figure 2 is a section on the line Figure l.

Referring to the drawings, the numeral l designates a portion of a vehicle wheel rim having secured thereto a metal band 2which, as l have shown in the drawings, is held to the rim by the bolts The band 2 has the flange 4f extending upwardly therefrom. Adapted to fit over the band 2 is a second band 5 also provided with an upwardly extending flange 6 which is parallel with the flange l of the band 2.

Each of the flanges 4f and 6 are provided v of holes through which the with a plurality hold both sections together.

bolts 7 pass and taining bars l2 are placed.

The springs 13 are spiral in forni and have one end encircling the bar l2 while the other end passes under one of the bolts 7 and encircles the adjacent bolt as indicated at 14C.

Assuming that one oit' the spring` members become broken and it is desired to replace same with a new spring, the bolts 7 are first removed which releases the coacting end of the springs and permits the flange 6 to be removed. llhe member 8 is then slipped ofi therim or band 2. ln order to remove the spring holding` bar the sides ot the member 8 are sprung apart.

A tire and rim as herein set forth and described is extremely simple to manufao ture, and it is thought that the construction, operation and many advantages of the herein described invention will be apparent 'to those skilled in the art.

Having thus fully described my invention, what l claim as new. and desire to secure by Letters/Patent, is

A tire ot the class described composed of an inverted ll-shaped member adapted to be movable between a pair o1" retaining ilanges,

a resilient tread portion secured to the outer y Wisconsin.

JACOB A. BRADLEY.
